Ingabe i-Schneier Method iyindlela enhle yokukhipha idatha?
Indlela ye-Schneier iyi-software-based data sanitization indlela esetshenzisiwe kwezinye izinhlelo zamafayili e- shredder kanye nedatha yokubhuqa ukubhala imininingwane ekhona kwi- hard drive noma amanye amadivaysi okugcina.
Ukulahla i-hard drive usebenzisa uhlelo lwe-Schneier data sanitization kuzovimbela zonke izindlela zokutakula zefayela ezisekelwe kwikhompyutha ukuthola ulwazi ku-drive futhi kungenzeka nokuvimbela izindlela eziningi zokutakula ezisetshenziswa kwi-hardware ukususa ulwazi.
Ngamafuphi, indlela ye-Schneier ibhala ngaphezulu kwedatha kwisitoreji sesitoreji ngenye, bese i-zero, futhi ekugcineni inezinombolo ezimbalwa zezinhlamvu ezingahleliwe. Kunemininingwane eminingi ngalokhu ngezansi, kanye nezibonelo ezimbalwa zezinhlelo ezifaka indlela ye-Schneier njengendlela yokukhetha lapho usula idatha.
Yenzani indlela yeSchneier?
Zonke izindlela zokunakekelwa kwedatha zisebenza ngezindlela ezifanayo kepha azisebenzi ngaso sonke isikhathi ngendlela efanayo. Isibonelo, indlela ye- Write Zero ibhala phansi idatha nge-zero kuphela. Abanye, njenge- Random Data , sebenzisa izinhlamvu ezingahleliwe. I-HMG IS5 ifana kakhulu nokuthi ibhala i-zero, bese iyedwa, bese isigqebhezana esingenangqondo, kodwa kudlula eyodwa kuphela ye-uhlamvu olungahleliwe.
Noma kunjalo, nge-Schneier indlela, kunenhlanganisela yamaphutha amaningi wezinhlamvu ezingahleliwe kanye nama-zero kanye nawo. Nansi indlela evame ukusebenza ngayo:
- Dlula 1: Ubhala eyodwa
- Dlula 2: Ubhala i-zero
- Dlula 3: Ubhala ukusakazwa kwezinhlamvu ezingahleliwe
- Dlula 4: Ubhala ukusakazwa kwezinhlamvu ezingahleliwe
- Dlula 5: Ubhala ukusakazwa kwezinhlamvu ezingahleliwe
- Dlula 6: Ubhala ukusakazwa kwezinhlamvu ezingahleliwe
- Dlula 7: Ubhala ukusakazwa kwezinhlamvu ezingahleliwe
Ezinye izinhlelo zingasebenzisa indlela ye-Schneier ngezinguquko ezincane. Isibonelo, ezinye izinhlelo zokusebenza zingase zisekele ukuqinisekiswa ngemva kokudlula kokuqala noma kokugcina. Lokho okwenzayo kuqinisekisa ukuthi umlingisi, njengomlingisi owodwa noma okungahleliwe, empeleni ubhalelwe ku-drive. Uma kwakungenjalo, isofthiwe ingakutshela noma iqala kabusha ngokuzenzakalelayo iphinde isebenzise ukudlula futhi.
Ithiphu: Kunezinhlelo ezithile ezikuvumela ukuba wenze ngokwezifiso amaphasiwedi, njengokwenza i-zero eyengeziwe ebhala ngemuva kokuPhepha 2. Noma kunjalo, uma wenza izinguquko ezanele kumzila we-Schneier, awuhlali ngempela leyo ndlela. Isibonelo, uma ususe amaphasiwedi amabili okuqala bese wengeza amathrekhi amaningana okungahleliwe okungahleliwe, ngabe uzokwakha indlela kaGutmann .
Izinhlelo ezixhasa Schneier
Izinhlelo eziningana ezehlukene vumela usebenzise indlela ye-Schneier ukusula idatha. Izibonelo ezimbalwa ziyi- Eraser , i- Fredly File Shredder , i- CBL Data Shredder , i-CyberShredder, i-Delete Files Unomphela, ne-Free EASIS Data Eraser.
Kodwa-ke, njengoba sishilo ngenhla, ezinye izinhlelo zefayili kanye nezinhlelo zokubhujiswa kwedatha zikuvumela ukuba wenze ngokwezifiso ukuthi kwenzekani ngesikhathi sokudlula. Lokhu kusho ukuthi ngisho noma bengenayo le ndlela itholakale, usengakwazi "ukwakha" indlela yeSchneier kulawo mahlelo usebenzisa isakhiwo esivela ngenhla.
Iningi lezinhlelo zokubhujiswa kwedatha lisekela izindlela eziningi zokuhlanza idatha ngaphezu kwesindlela se-Schneier. Uma ufuna, kungenzeka ukuthi ukhethe indlela ehlukile yokwenza idatha uma usuvulekile uhlelo.
Ulwazi oluthe xaxa ku-Schneier Method
Indlela ye-Schneier eyadalwa nguBruce Schneier futhi yabonakala encwadini yakhe ethi Applied Cryptography: I-Protocol, I-Algorithms, ne-Code Code ku-C (i-ISBN 978-0471128458).
UBruce Schneier une-website ebizwa nge-Schneier ku-Security.
Sibonga ngokukhethekile kuBrian Szymanski ngokucaciswa kwemininingwane ethile kulolu chungechunge.
